Operating Environment 

 

 

1. Do not use in an atmosphere having corrosive gases, 

chemicals, sea water, water, water steam, or where 
there is direct contact with any of these. 

2. Do not use in an environment where flammable gas 

or explosive gas exists. Usage may cause a fire or 
explosion. The products do not have an explosion 
proof construction.

 

3. Do not use in a place subject to heavy vibration 

and/or shock. 

4. The valve should not be exposed to prolonged 

sunlight. Use a protective cover. Note that the valve 
is not for outdoor use. 

5. Remove any sources of excessive heat. 
6. If it is used in an environment where there is 

possible contact with oil, weld spatter, etc., exercise 
preventive measures. 

7. When the solenoid valve is mounted in a control 

panel or its energized for a long time, make sure 
ambient temperature is within the specification of 
the valve. 

 
 
1. Temperature of ambient environment 

Use the valve within the range of the ambient temperature 
specification of each valve. In addition, pay attention when 
using the valve in environments where the temperature 
changes drastically. 

2. Humidity of ambient environment 

• When using the valve in environments with low humidity, take 

measures to prevent static. 

• If the humidity rises, take measures to prevent the adhesion of 

water droplets on the valve. 

 
 

Maintenance 

 

 

1. Perform maintenance inspection according to the 

procedures indicated in the operation manual. 

If handled improperly, malfunction and damage of machinery or 
equipment may occur.

   

2.   Removal of equipment, and supply / exhaust of 

compressed air 

When components are removed, first confirm that measures are 
in place to prevent workpieces from dropping, run-away 
equipment, etc. Then, cut off the supply pressure and electric 
power, and exhaust all compressed air from the system using 
the residual pressure release function. 
For 3-position closed center, exhaust the residual pressure 
between the valve and the cylinder. 
When the equipment is operated after remounting or 
replacement, first confirm that measures are in place to prevent 
lurching of actuators, etc. Then, confirm that the equipment is 
operating normally. 
 
 
 

 
 
 

3. Low frequency operation 

Valves should be operated at least once every 30 days to 

prevent malfunction. (Use caution regarding the air supply.) 

4. Manual override 

When the manual override is operated, connected equipment will 
be actuated. 

Operate after safety is confirmed. 

5. If the volume of air leakage increases or the valve 

does not operate normally, do not use the valve. 
Perform periodic maintenance on the valve to 
confirm the operating condition and check for any air 
leakage. 

 
 

1. Drain flushing 

Remove drainage from the air filters regularly. (Refer to the 
specifications.) 

2. Lubrication 

In the case of rubber seals, once lubrication has been started, it 

must be continued. Use class 1 turbine oil (with no additives), 

VG32. If other lubricant oil is used, it may cause a malfunction. 

Please contact SMC for information on the suggested class 2 

turbine oil (with additives), VG32. 

3. Manual override operation 

When switching a double solenoid valve via the manual override 

operation, instantaneous operation may cause the       

malfunction of the cylinder. It is recommended that the manual 

override be held until the cylinder reaches the stroke end 

position.
